- Objective: To provide evidence-based recommendations for the management of exocrine pancreatic insufficiency (EPI) after pancreatic surgery. Background: EPI is a common complication after pancreatic surgery but there is certain confusion about its frequency, optimal methods of diagnosis, and when and how to treat these patients. Methods: Eighteen multidisciplinary reviewers performed a systematic review on 10 predefined questions following the GRADE methodology. Six external expert referees reviewed the retrieved information. Members from Spanish Association of Pancreatology were invited to suggest modifications and voted for the quantification of agreement. Results: These guidelines analyze the definition of EPI after pancreatic surgery, (one question), its frequency after specific techniques and underlying disease (four questions), its clinical consequences (one question), diagnosis (one question), when and how to treat postsurgical EPI (two questions) and its impact on the quality of life (one question). Eleven statements answering those 10 questions were provided: one (9.1%) was rated as a strong recommendation according to GRADE, three (27.3%) as moderate and seven (63.6%) as weak. All statements had strong agreement. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.

- Background: Contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) and quantitative-elastography endoscopic ultrasound (QE-EUS) are considered useful tools for the evaluation of solid pancreatic tumors (SPT). The aim of our study was to evaluate the diagnostic accuracy of CEH-EUS, QE-EUS, and the combination of both for the differential diagnosis of SPT. Methods: Sixty-two consecutive patients (mean age 64.3 years, range 32-89 years, 44 male) who underwent EUS for the evaluation of SPT were prospectively included. EUS was performed with a linear Pentax-EUS and a Hitachi-Preirus processor. The mass (area A) and a reference area B were selected during QE-EUS, and results expressed as B/A (strain ratio). A strain histogram of the mass was also evaluated. Microvascularization of the tumor was evaluated over 2min during CEH-EUS after intravenous injection of 4.8mL SonoVue. Final diagnosis was based on histopathology of surgical specimens or EUS-guided tissue acquisition and clinical follow-up in non-operated cases. Diagnostic accuracy of CEH-EUS, QE-EUS, and their combination was calculated. Results: Median size of the masses was 32 mm (range 12-111). Final diagnosis was pancreatic adenocarcinoma (n=45), neuroendocrine tumor (n=3), inflammatory mass (n=10), pancreatic metastasis (n=2), autoimmune pancreatitis (n=1), and a mucinous cystadenocarcinoma (n=1). Overall accuracies for determination of malignancy using QE-EUS, CEH-EUS, their combination, and EUS-guided tissue acquisition were 98.4% (95% confidence interval (CI): 91.4-99.7), 85.5% (95% CI: 74.7-92.2), 91.9% (95% CI: 82.5-96.5), and 91.5% (95% CI: 83.6-99.5), respectively. Conclusion: The combination of QE-EUS and CEH-EUS is a useful tool for the differential diagnosis of SPT, giving complementary information. However, this combination does not significantly increase the diagnostic accuracy of either of the techniques performed alone.

- Background: diagnosis of early chronic pancreatitis (CP) is hampered due to the low accuracy of current imaging techniques and the absence of methods for histological confirmation. We aimed to evaluate the efficacy of endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for the histological diagnosis of early CP. Methods: a prospective, cross-sectional, single-center study was designed. Consecutive patients referred for EUS with a clinical suspicion of CP were evaluated for inclusion into the study. Inclusion criteria were age > 18 years and indeterminate EUS findings for the diagnosis of CP according to the Rosemont classification. EUS-FNB of the body of the pancreas was performed with Procor(TM) needles.Tissue samples were immersed into a methanol-based buffered preservative solution for cytohistological evaluation.The quality of the samples obtained and the histological findings were evaluated. Procedure-related complications were recorded. Results: the study was stopped after eleven patients were included due to safety concerns and poor diagnostic yield. The mean age of the patients was 50.3 years (range 33-70 years) and six were male. Samples were of poor quality in five cases, but were sufficient for cell-block evaluation. An inflammatory infiltration with mild fibrosis was identified in two cases and neither inflammatory infiltration nor fibrosis was identified in three cases. With regard to the other six cases, isolated inflammatory cells were observed in one case, although the cellularity was poor and unsuitable for cytological evaluation in five cases.There was one major complication (9.1%) of acute pancreatitis that required hospitalization for 48 hours. Conclusion: EUS-FNB is technically feasible in patients with EUS findings categorized as indeterminate for a CP diagnosis. However, the diagnostic yield is poor and there is a non-negligible risk of complications.

- Refeeding after acute pancreatitis (AP) is traditionally started in a successively increasing manner when abdominal pain is absent and pancreatic enzymes are decreasing. We aimed to evaluate length of hospital stay (LOHS) and refeeding tolerance for early refeeding and/or immediately full caloric intake in patients recovering from AP. Methods: In this randomized, open-label trial, patients with AP were randomized into four different refeeding protocols. Group 1 and 2 received a stepwise increasing diet during three days while 3 and 4 received an immediately full caloric, low fat diet. Group 2 and 4 started refeeding early (once bowel sounds returned) and 1 and 3 started at standard time (bowel sounds present, no abdominal pain, no fever, leucocytes and pancreatic enzymes decreasing). Main outcomes measurements were LOHS and tolerance (ability to ingest >50% of meals without severe pain, nausea or AP relapse). Results: Eighty patients were evaluated and 72 randomized (median age 60 years, range 24-85, 33 male). LOHS was significantly reduced after early refeeding (median 5 versus 7 days (p = 0.001)) but not in patients receiving immediately full caloric diet, compared to standard management (6 versus 6 days (p = 0.12)). There was no difference in refeeding tolerance comparing immediately full caloric diet versus stepwise increasing diet (31/35 (89%) versus 33/37 (89%) patients tolerating the treatment, p = 1.00) or early versus standard time for refeeding (33/37 (89%) versus 31/35 (89%), (p = 1.00)). Conclusions: Refeeding after AP when bowel sounds are present with immediately full caloric diet is safe and well tolerated. Early refeeding shortens LOHS. Copyright (C) 2014, IAP and EPC.

Tidskriftsartikel (refereegranskat)abstract
- Background and Objectives: Previous reports assessing the reproducibility of endoscopic ultrasound elastography (EUS-E) in evaluation of solid pancreatic lesions (SPL) involved only experienced endosonographers. We aimed to assess the interobserver agreement (IOA) of EUS-E in the evaluation of SPL by endoscopists with different levels of experience in EUS and EUS-E. Materials and Methods: A cross-sectional observational multicenter study was designed and included 11 endoscopists who were divided into four groups: Group A (long experience in EUS and EUS-E); Group B (short experience in EUS and EUS-E); Group C (long experience in EUS and no experience in EUS-E); and Group D (no experience in EUS or EUS-E). The observers independently classified the patterns of 60 video sequences of EUS-E, after a 20-min training session. For each group, we calculated IOA (kappa statistic, k) of EUS-E and the diagnostic accuracy of EUS-E for pancreatic malignancy, by comparing the pattern of EUS-E indicative of malignancy (heterogeneous or homogenous blue) with the final diagnosis. Results: The overall IOA was moderate (k = 0.42; 95% confidence interval (CI) 0.33-0.52). The IOA of Group A (k = 0.80; 95% CI 0.65-1.00) was significantly higher than that of Groups B (k = 0.54; 95% CI 0.40-0.71), C (k = 0.54; 95% CI 0.39-0.68), and D (k = 0.28; 95% CI 0.14-0.40). IOA of Groups B and C was not significantly different, but it was significantly higher than that of Group D. The diagnostic accuracy of Group A (area under the curve under summary receiver operating characteristic (AUROC) = 0.83; 95% CI 0.75-0.90) was not significantly different from that of Group B (AUROC = 0.77; 95% CI 0.71-0.83), but it was significantly higher than that of Groups C (AUROC = 0.74; 95% CI 0.67-0.81) and D (AUROC = 0.74; 95% CI 0.67-0.81). No significant difference was seen between Groups B, C, and D for diagnostic accuracy. Conclusion: EUS-E is reproducible in the evaluation of SPL, even between endoscopists with no or limited experience in EUS and/or EUS-E. Reproducibility and diagnostic accuracy increase with experience in EUS and EUS-E.

Tidskriftsartikel (refereegranskat)abstract
- Background: Little is known about risk factors for complications in chronic pancreatitis (CP). High fat diet (HFD) has been demonstrated to aggravate pancreatic injury in animal models. The aim of this study was to investigate the role of HFD in age at diagnosis of CP and probability of CP related complications. Methods: A cross-sectional case-case study was performed within a prospectively collected cohort of patients with CP. Diagnosis and morphological severity of CP was established by endoscopic ultrasound. Pancreatic exocrine insufficiency (PEI) was diagnosed by C-13 mixed triglyceride breath test. Fat intake was assessed by a specific nutritional questionnaire. Odds ratios (OR) for CP related complications were estimated by multivariate logistic regression analysis. Results: 168 patients were included (128 (76.2%) men, mean age 44 years (SD 13.5)). Etiology of CP was alcohol abuse in 89 patients (53.0%), other causes in 30 (17.9%) and idiopathic in the remaining 49 subjects (29.2%). 24 patients (14.3%) had a HFD. 68 patients (40.5%) had continuous abdominal pain, 39 (23.2%) PEI and 43 (25.7%) morphologically severe CP. HFD was associated with an increased probability for continuous abdominal pain (OR = 2.84 (95%Cl, 1.06-7.61)), and a younger age at diagnosis (37.0 +/- 13.9 versus 45.8 +/- 13.0 years, p = 0.03) but not with CF related complications after adjusting for sex, years of follow-up, alcohol and tobacco consumption, etiology and body mass index. Conclusions: Compared with a normal fat diet, HFD is associated with a younger age at diagnosis of CP and continuous abdominal pain, but not with severity and complications of the disease.

- Diagnosis of chronic pancreatitis (CP) remains a challenge. Endoscopic ultrasound (EUS) can be considered nowadays as the technique of choice for the morphological diagnosis of this disease. More than three or four EUS defined criteria of CP need to be present for the diagnosis of the disease. The development of the more restrictive Rosemont classification aims to standardize the criteria, assigning different values to different features but its impact on the EUS-based diagnosis of CP is debatable. A combined use of endoscopic function test and EUS has even increased the diagnostic yield. Elastography and FNA may be also of help for diagnosing CP. EUS also provides with very valuable information on the severity of the disease, giving key information that may influence in the treatment. Differential diagnosis of solid pancreatic masses in the context of a CP is also challenging, EUS plays a key role in this context. It provides with the possibility of obtaining specimens for histopathological diagnosis. Nowadays, new developed techniques associated to EUS, like elastography and contrast enhancement, are also showing promising results for the differentiating between these pancreatic lesions.

- Differential diagnosis of solid pancreatic lesions remains as an important clinical challenge, mainly for the differentiation between mass forming chronic pancreatitis, autoimmune pancreatitis and pancreatic adenocarcinoma. Endoscopic ultrasound (EUS), computed tomography (CT) and magnetic resonance imaging (MRI) can all provide valuable and complementary information in this setting. Among them, EUS has the unique ability to obtain specimens for histopathological diagnosis and can therefore play a crucial role in the evaluation patients with inconclusive findings on initial examinations. Nowadays, new developed techniques associated to EUS, like elastography and contrast enhancement, have shown promising results for the differential diagnosis of these pancreatic lesions.

- Objectives Several recent studies have demonstrated the association between smoking and chronic pancreatitis (CP). However, less is known about the role of smoking in the development of CP-related complications. Our aim was to investigate the impact of smoking and alcohol consumption on age of onset and complications at CP diagnosis. A cross-sectional case-case study was performed within a prospectively collected cohort of patients with CP. Alcohol consumption and smoking habits were assessed using a standardized questionnaire. Morphologic severity was defined based on endoscopic ultrasound criteria for CP and classified as mild (3-4 criteria), moderate (5-6 criteria), and severe (>= 7 criteria or calcifications). Pancreatic exocrine insufficiency (PEI) was diagnosed using the C-13-mixed triglyceride breath test. Odds ratios (OR) with 95% confidence intervals (CI) for CP-related complications were calculated using a case-case design. A total of 241 patients were included. Smoking was associated with PEI (OR [95% CI], 2.4 [1.17-5.16]), calcifications (OR [95% CI], 2.33 [1.10-4.95]), and severe morphologic changes (OR [95% CI], 3.41 [1.31-8.85]) but not with pseudocysts or diabetes. Neither smoking nor alcohol consumption was associated with age of onset. Tobacco, but not alcohol, is associated with PEI, calcifications, and severe morphologic (>= 7 criteria or calcifications) CP at diagnosis. Smoking cessation should be encouraged in patients with CP.

- Endoscopic ultrasound (EUS) is a reference technique for diagnosing and staging several different diseases. EUS-guided biopsies and fine needle aspirations are used to improve diagnostic performance of cases where a definitive diagnosis cannot be obtained through conventional EUS. However, EUS-guided tissue sampling requires experience and is associated with a low but not negligible risk of complications. EUS elastography is a non-invasive method that can be used in combination with conventional EUS and has the potential for improving the diagnostic accuracy and reducing the need for EUS-guided tissue sampling in several situations. Elastography measures tissue stiffness by evaluating changes in the EUS image before and after the application of slight pressure to the target tissue by the ultrasonography probe. Pathologic processes such as cancerization and fibrosis alter tissue elasticity and therefore induce changes in elastographic appearance. Qualitative elastography depicts tissue stiffness using different colors, whereas quantitative elastography renders numerical results expressed as a strain ratio or hue histogram mean. EUS elastography has been proven to differentiate between benign and malignant solid pancreatic masses, as well as between benign and malignant lymph nodes with a high accuracy. Studies have also demonstrated that the early changes of chronic pancreatitis can be distinguished from normal pancreatic tissues under EUS elastography. In this article, we review the technical aspects and current clinical applications of qualitative and quantitative EUS elastography and emphasize the potential additional indications that need to be evaluated in future clinical studies.
